Method in reeling up and a reel-up

ABSTRACT

Before a reel change a new core ( 5 ) is brought to a change station. When the old reel (R) is full, the web is changed to travel to the new core periphery and primary reeling beings. The web forms a reel through a reeling nip (N 1 ) between the loop of an endless supporting member ( 1 ) and the core. A change is made to secondary reeling, where a portion of the supporting member ( 1 ) brings the web to the reel, to move over to the reel in a nip (N) between said portion and the reel outer periphery. The core ( 5 ) is transferred so the nip (N) moves forward. A first guide roll ( 2 ) is transferred towards the core periphery so the distance of the nip (N 1 ) located between the core ( 5 ) and the loop of the supporting member ( 1 ) from the first guide roll ( 2 ) changes in the primary reeling.

The invention relates to a method in reeling up, which is of the typepresented in the preamble of the appended claim 1. The invention alsorelates to a reel-up, which is of the type presented in the preamble ofthe appended claim 10.

In the final end of a paper machine or a finishing apparatus for paper,a typically several meters wide paper web, which has been producedand/or treated in earlier machine sections, is reeled around a reelspool to form a machine reel. In this reeling up process a reelingcylinder that is journalled rotatable is typically used for guiding thepaper web on the machine reel, wherein the nip contact between thereeling cylinder and the machine reel is utilized to influence thequality of the reel produced thereby. A conventional solution is the onein which the reeling cylinder remains stationary and the reel spoolaround which the reel is accumulated in nip contact is moved duringreeling up in the supporting structure, for example by supporting theends of the reel spool on reeling rails. The ends of the reel spool areaffected with a suitable loading mechanism to adjust the nip contactbetween the machine reel that is being formed and the reeling cylinder.Such reeling concepts and loading methods related thereto are disclosed,for example, in the Finnish patent 91383 and in the corresponding U.S.Pat. No. 5,251,835, as well as in the Finnish patent application 950274and in the corresponding U.S. Pat. No. 5,690,298.

Another known solution is the one in which the reeling cylinder isarranged to move on a carriage, and the machine reel is rotated withcenter drive in a stationary reeling station, i.e. the center of thereel spool remains in the same location. When the radius of the machinereel increases, the reeling cylinder shifts in such a manner that thecarriage supporting the same moves in the guide. Such an arrangement isknown, for example, from the European application publication 792829 andin the corresponding U.S. Pat. No. 5,988,557.

The U.S. Pat. No. 5,370,327 discloses a solution in which the reelingcylinder moves in the vertical direction, thus making it possible tomaintain the angular position of the nip between the reeling cylinderand the machine reel constant when the reel moves on the reeling rails.The low position of the reeling cylinder and the movement of the same inthe vertical direction enable the transfer of the reel spools from astorage to a reeling station along a straight transfer path. Thesolution contains two pairs of reeling carriages, of which the pair thathas delivered a full machine reel can return past the other pair that isguiding the reel to be reeled, to retrieve a new empty reel spool.

In addition to the stationary reeling cylinder that guides the web onthe reel, according to the Finnish patent application 950274 and thecorresponding U.S. Pat. No. 5,690,298 it is possible to use an auxiliaryroll located at a lower position and moving in the vertical direction,said auxiliary roll forming a second nip with the machine reel formed inthe moving reeling station. Before the change this auxiliary roll is incontact with the reel that is becoming full, which has been run off thereeling cylinder. A corresponding arrangement in connection with achange is disclosed in the Finnish patent 91383/U.S. Pat. No. 5,251,835.

In addition, from publication EP-860391 is known a reel-up, in which theweb is guided on a reel via a belt or a wire, which is led via guiderolls. Thus, by means of the belt or the wire, a long reeling nip havingan even pressure is provided on the area of the lower half of the reel.The pressure can be adjusted through the tension of the belt or thewire. The belt or wire loop can be tilted in the vertical plane in sucha manner that the first guide roll in the travel direction of the webcan be lifted against the new reel spool, which rests on the reelingrails above the belt. When growing, the reel moves forward on thereeling rails in such a manner that it is continuously in contact withthe downwards-tilted run of the wire or belt, which follows the guideroll and via which the web comes on the reel.

In addition, from the patent U.S. Pat. No. 5,531,396 is known a reel-up,in which the wire loop is guided over the reeling cylinder in such amanner that it guides the web after the reeling cylinder on the reelbeing formed.

The problem with the reel-ups using a wire or a belt is the change fromreeling by a hard nip (by means of a guide roll) over to wire or beltreeling when forming the bottom of the reel in primary reeling. Thisrequires possibilities for movement from the primary reeling device,both in the vertical and horizontal direction.

The purpose of the invention is to provide a new reeling up method usinga belt and a wire, by means of which the reeling up of a bottom can bebetter implemented, simultaneously preserving the advantages of knownmethods. To attain this purpose, the method according to the inventionis primarily characterized in what will be presented in thecharacterizing part of the appended claim 1. The first guide roll istransferred in the peripheral direction of the reel spool against theincoming direction of the web. Thus, it is possible to implement thereeling up of the bottom first with a hard nip and after the transferwith a softer nip. Thus, the reel spool does not need to be transferredduring primary reeling. The reel-up according to the invention, in turn,is characterized in what will be presented in the characterizing part ofthe appended claim 10.

As for the other embodiments of the invention and the advantages of thesame, reference is made to the appended dependent claims and to thedescription hereinbelow.

In the following, the invention will be described in more detail withreference to the appended drawings, in which

FIG. 1 illustrates schematically the main principle of the reel-up in aside view,

FIGS. 2 to 6 illustrate the different stages of the reeling up processin a side view of the reel-up, and

FIGS. 7 to 11 illustrate the different stages of the reeling up processin a side view of the reel-up according to a second embodiment.

FIG. 1 illustrates a continuously operating reel-up, where the paper webW coming from a preceding section of a paper machine or a finishingapparatus for paper, which web is normally several metres wide, travelsvia the reeling nip N onto the reel R. The reeling nip is formed bymeans of a flexible supporting member 1 in the form of an endless loop,such as a belt or a wire. The supporting member 1 is guided over twoguide rolls 2 and 3, at each of which the run of the member 1 turns tothe opposite direction. In the travel direction of the web the firstguide roll 2 can form a “hard nip” with the reel being started in theinitial stage of reeling up in such a manner that the supporting member1 is in contact with the reel at a point where the member travelssupported by the guide roll 2 on the surface of the roll. The latterguide roll 3 or the first guide roll 2 can be a driven roll, i.e. atraction roll, or separate drives can be arranged for both rolls. Theweb travels guided by the supporting member 1 onto the machine reel R,which is formed around a reel spool 5 rotatable with its own centerdrive. It is possible for the reel spool 5 to move in the machinedirection with respect to the loop of the supporting member 1, and thisis arranged in such a manner that the bearing housings at the ends ofthe reel spool that enable the rotation of the reel spool 2 aresupported with suitable supporting structures. In connection with thereel-up, there is also a storage of empty reel spools 5 (not shown),from where the rolls are brought to the change station at the firstguide roll 2 in order to change the web going to the machine reel R thatis becoming full. The reel change takes place at production speed i.e.the paper web passed at high speed to the full reel is changed to travelonto a new reel spool brought to the change station.

The machine reel R can be transferred in the machine direction in atransfer device 7, which supports the bearing housings at the ends ofthe reel spool and which is moved by means of actuators attached to theframe of the reel-up. The transfer device 7 is arranged to move onsubstantially horizontal reeling rails 6 extending in the machinedirection, and it is formed of a carriage at each end of the reel spool,which supports the bearing housing at the end of the reel spool 5. Whenthe diameter of the machine reel R increases, and the reel movesforward, it is in continuous contact with the supporting member 1because the transfer path of the transfer device 7 and the web-carryingportion of the supporting member 1 together form an angle opening in thetransfer direction. In FIG. 1, the upper, web-carrying portion of theloop of the supporting member 1 is directed diagonally downwards in itsdirection of movement, whereas the transfer path of the reel R (and thereel spool 5) is substantially horizontal.

FIG. 2 illustrates a situation in the primary stage of reeling up in asituation where the reel spool 5 and the reel R formed around it duringprimary reeling is transferred from the primary reeling device 8 to thetransfer device 7, which operates as a secondary reeling device. Forthis, the transfer device 7 is run in the direction pointed out by thearrow against the travel direction of the web to a point close to theprimary reeling device 8. In this stage the web W travels to the reel Rvia the portion of the supporting member 1 coming after the first guideroll 2.

FIG. 3 illustrates a situation where the transfer device 7 istransferred along the reeling rails 6 forward in the travel direction ofthe web according to the increase in the diameter of the reel R so thatthe reel is, at its lower side, always in contact with the loop of thesupporting member 1 in such a manner that the web moves over to theouter periphery of the reel R in the reeling nip N between theweb-carrying portion of the loop and said outer periphery. The reelspool 5 forming the core of the new reel is brought to the primaryreeling device 8. FIG. 3 also illustrates a situation, where the loop ofthe supporting member 1 has been transferred forward in the machinedirection in such a manner that the first guide roll 2 is locateddirectly below the new reel spool 5. The movements of the first guideroll 2 and the loop are described more in detail hereinbelow.

FIG. 4 illustrates a situation, where the new reel spool 2, byvertically lowering the primary reeling device 8, has been brought tothe change station in contact with that portion of the loop of thesupporting member 1 that travels on the first guide roll 2 in order tocreate a so-called hard nip. Before this the new reel spool 5 has beenaccelerated to the web speed with the drive of the primary reelingdevice 8. In the change station the plane connecting the central axis ofthe reel spool 5 and the central axis of the guide roll 2 issubstantially vertical. In comparison to the situation of FIG. 3, theold machine reel R in the secondary reeling has moved forward accordingto the increase in the reel diameter, i.e. the reeling nip N between thereel R and the loop of the supporting member has moved to the traveldirection of the upper portion of the loop. The paper web W now travelsbetween the new empty reel spool 5 and the first guide roll 2 of theloop, and further along the upper web-carrying portion of the loop ofthe supporting member 1 and moves over to the periphery of the old reelR in the reeling nip N. FIG. 4 further illustrates how in this stage theold reel R has come into contact with a press roll 9 that is journalledrotatable and rotated with a drive of its own, the purpose of which isthe ensure the density of the surface layers of the reel. The nipthrough which the web travels between the supporting member 1 and theshell of the new reel spool 5 is marked with the reference N1.

FIG. 5 illustrates a situation where the web going to the old reel R hasbeen changed to travel around the new reel spool 5, i.e. after the nipN1 between the reel spool 5 and the first guide roll 2, the web followsthe surface of the new reel spool 5 and begins to form a new machinereel R around it, in which case the above-mentioned nip N1 forms areeling nip in the primary reeling. The change methods that are notdescribed more in detail here may comprise suitable blowings of air, bymeans of which the web is brought to tear and to be guided around thenew reel spool 5. The change is performed in a know manner at full webspeed, i.e. at the production speed of the web. The reel spool 5 is inthe primary reeling device 8 during the change.

FIG. 5 presents how the end point of the secondary reeling of the oldreel R is before the second guide roll 3 (the location of the nip N). Itis also possible to continue the secondary reeling in such a manner thatthe reeling nip N moves all the way to the end of the downwardlydiagonal portion of the loop of the supporting member 1 over the secondguide roll 3.

FIG. 6 illustrates a situation where the old full machine reel R hasbeen transferred with the transfer device 7 forward to the removalstation away from the contact with the loop of the supporting member 1while the press roll 9 moves according to the transfer movement in sucha manner that it is in continuous contact with the surface of themachine reel R. When the old machine reel R has been transferred off theloop of the supporting member and when a layer of a certain thicknesshas been gathered around the new reel spool 5 in the first primaryreeling stage, the loop of the supporting member 1 is transferred in amanner pointed out by the arrow in the peripheral direction of the reelspool against the incoming direction of the web in such a manner thatthe first guide roll 2 moves further away from the new reel, and theperipheral surface of the reel comes against the loop in the freeportion of the supporting member 1 following immediately the guide roll2, i.e. the situation is the same as in FIG. 2. The new reel spool is inthis stage still in the primary reeling device 8. The reeling nip N1therefore moves in relation to the guide roll 2 in the travel directionof the supporting member 1.

The incoming direction of the web here refers to the direction in whichit enters the reeling nip between the loop of the supporting member 1and the reel spool 5. The web W can thus either come guided by the firstguide roll 2 on that portion of the loop of the supporting member thatcurves over the guide roll 2 (in the manner presented in FIGS. 4 to 6,where entry of the web to the loop is guided by a web guide roll 10before the loop), or it can also come to the nip guided by the reelspool 5 and the web layers on top of it, i.e. it is first guided alongthe surface of the reel before entering the reeling nip N1.

When the full reel R has been removed from the reel-up, the transferdevice 7 is free to move on the rails 6 towards the primary reelingdevice 8 into the position of FIG. 2, where the reel spool 5 in theprimary reeling device 8 and the reel R that has started to form aroundit are delivered to the transfer device 7 for secondary reeling. Thesecondary reeling of this new reel R then proceeds again along the upperweb-carrying portion of the loop of the supporting member 1 according toFIGS. 2 to 6. During secondary reeling the guide roll 2 is transferredagain back in the travel direction of the web (from the position of FIG.2 to the position of FIG. 3), i.e. to a location where it will be when anew reel spool is brought to the change station again.

It is to be noted that the nip contact with the supporting member 1 iscontinuous during the entire reeling up, i.e. when changing from primaryreeling to secondary reeling the nip contact to the loop of thesupporting member is continuously maintained when the reel spool 5 isdelivered from the primary reeling device 8 to the transfer device 7.The transfer device 7 can start to convey the reel spool 5 and the reeldirectly forward from that fixed position where the primary reelingdevice 8 has kept the reel spool 5 at the change moment and during theentire primary reeling. When the reel spool 5 is delivered from theprimary reeling device 8 to the transfer device 7, the torque rotatingthe reel spool 5 can be changed from the drive of the primary reelingdevice 8 to the drive of the transfer device 7 in previously knownmanners. The drive of the transfer device 7 moves along with thetransfer device and rotates the reel spool 5 and the reel R around itduring the secondary reeling at a speed required by the productionspeed, until the full reel starts to decelerate after the web cutting.

Transferring the first guide roll 2 against the incoming direction ofthe web W achieves the advantageous effect that the location where theloop of the supporting member 1, such as a belt or a wire, is againstthe periphery of the new reel that has started to form around the reelspool 5 is shifted from the guide roll 2 to the free portion of thesupporting member 1 following after it. The same relative shift could,in fact, be achieved by transferring the reel spool 5 in the primaryreeling device forward in the conveying direction of the belt loop.However, a drawback in this case is that in the primary reeling it wouldbe necessary to guide the movement of such a reel spool 5 whose masschanges continuously because of the web W gathered around it. Whenoperating with the method according to the invention, the central axisof the reel spool 5 can be kept in fixed position in this transfer stageof the reeling nip and even during the entire primary reeling. This, inturn, makes it possible to form the primary reeling device 8 stationaryat least in such a manner that it can be moved only according to onetransfer path that is substantially vertical, but it is not necessary toarrange a possibility for horizontal movement for it in order totransfer the reel spool 5 in the direction of the supporting memberloop.

There are also other advantages in the movement possibility of the guideroll 2 in the peripheral direction of the reel spool 5. When theposition of the guide roll 2 can be changed in the manner describedhereinabove, it is firstly possible to select whether the reeling up ofthe bottom around a new reel spool 5 is started directly against thehard reeling nip N1 (against the supporting member 1 travelling over thefirst guide roll 2), or directly solely against the supporting member 1(the free portion of the supporting member following after the beltguide roll 2), i.e. against the “soft” reeling nip N1. In order toselect this starting position it is not necessary to transfer the reelspool 5, but it can be lowered to the change station with the primaryreeling device 8 always along the same transfer path, and the startingposition only depends on the position to which the first guide roll 2has been driven. When the web has been changed to travel on the reelspool 5 in the change station, the reeling of the bottom is startedimmediately against either the hard nip or the soft nip.

Advantageously the procedure is such that after the change, in the firstprimary reeling stage, the bottom of the reel, i.e. the first weblayers, around the reel spool 5 start to be reeled against the hard nipN1 while the reel spool 5 remains in the change station, and after thisa second primary reeling stage is entered by transferring the firstguide roll 2 in relation to the reel spool 5, after which the bottom isreeled against the soft nip N1.

By transferring the guide roll 2 in the machine direction, a suitablestarting point is found, where the guide roll is located during thechange and the first primary reeling stage. When the web has beenchanged and the reel begins to increase around the new reel spool, theguide roll 2 is moved in the vertical direction downwards according tothe increase of the reel, and by means of this movement, also the linearload of the reeling nip in the first primary reeling stage is adjusted.

FIG. 1 illustrates schematically the movement possibilities of the firstguide roll 2 and the second guide roll 3. The first guide roll 2, bymeans of which the location of the reeling nip can be determined in theprimary reeling, is advantageously movable both in the verticaldirection and in the horizontal direction in directions perpendicular toits axis of rotation in such a manner that the transfer movements inthese directions are independent of each other. Thus, the guide roll 2can be located in an accurately selected point in a vertical planecoinciding with the travel direction of the web within an area ofcertain size, and the transfer from the first point to a second can beimplemented over a desired transfer path. The same possibility formovement exists also with the second guide roll 3. In practice, themovement in the case of both guide rolls can be implemented by attachingthe roll rotatably to a first element and movably in it linearly in onedirection in the above-mentioned vertical plane, and arranging in turnsaid element movably linearly in a direction perpendicular to this firstdirection in the same vertical plane. An element of this kind is at bothends of the roll on the edge of the reel-up.

In an embodiment according to FIGS. 2 to 7, the entire loop 1 of thesupporting member 1 must move according to the movement of the firstguide roll 2, i.e. the second guide roll 3 must follow the movement ofthe first guide roll 2 in such a manner that the desired position of theloop is kept. This can be implemented in such a manner that the axes ofrotation of the first guide roll 2 and the second guide roll 3 areinterconnected with a rigid connecting body, which is schematicallyillustrated by the dotted line in FIG. 1. In practice, the movements canfurther be implemented in such a manner that each guide roll is mountedmovably in the height direction in the carriage of its own, which inturn can be transferred in the machine direction in the frame of thereel-up. Thus, for example, by actively moving the carriage of the firstguide roll 2 and by actively adjusting the height position of the guideroll 2 in the carriage, the guide roll can always be placed in thecorrect position in relation to the primary reeling device 8 and thereel spool in it 5. The second guide roll 3 follows the movement of thefirst guide roll in such a manner that the angle of the loop of thesupporting member in relation to the horizontal plane changes in adesired manner or remains constant. In practice, the movement of thesecond guide roll 3 must be actively guided only in one direction, andthe roll will automatically position itself in a direction perpendicularto said direction due to the rigid connecting body. For example, whentransferring the carriages of the first guide roll 2 with activeactuators and when adjusting the height position of the roll 2 in thecarriages with the active actuators of these carriages, only height hasto be actively adjusted in the carriage of the second roll 3, and thecarriages follow the movement of the first roll 2 automatically in themachine direction via the rigid connecting body.

The tension of the supporting member 1, which is one of the manipulatedvariables during primary reeling and especially during secondaryreeling, can be implemented, for example, with a tension roll attachedin a movable manner to the connecting body of the rolls and in contactwith the loop of the supporting member 1.

A second possibility to arrange the movement of the loop of thesupporting member is to arrange the guide rolls 2 and 3 movably in sucha manner that they are not connected together via a rigid connectingbody which would determine the distance between their center-points, butthey are movable completely independently of each other, within thelimits set by the loop. The possibilities of movement for both rolls canbe the same as above, e.g. they can be moved both in the heightdirection and the machine direction, but by means of their mutualmovement it is now possible to adjust the tension of the supportingmember 1 as well.

As can be seen from the figures, the primary reeling device can be movedin a vertical direction along the vertical guides in the frame of thereel-up, i.e. the movement is linear. The locking jaws of the primaryreeling device, to which the bearing housings of the new reel spool 5can be attached are directed from this frame to that direction where thereel is to be transferred during secondary reeling, i.e. the transferdirection of the transfer device 7. The nip N1 between the new reelspool 5 and the supporting member 1 can be closed by lowering theprimary reeling device and by keeping the first guide roll 2 and theloop of the supporting member in that position where it has beentransferred earlier, or by keeping the primary reeling device 8 at itsplace and by lifting the first guide roll 2 up until the web remainsbetween the supporting member 1 and the reel spool 5.

FIGS. 7 to 11 illustrate a reel-up where the stages are principally thesame as the ones described hereinabove. In addition to the first guideroll 2 and the second guide roll 3, there is, however, a third rollinside the loop of the supporting member 1, an additional roll 11, whichis located in the travel direction of the web before the first guideroll 2. At the first guide roll 2 the travel direction of the loop doesnot change to the opposite, but the diagonally upward directed portionof the supporting member 1 turns to a diagonally downward directedportion, along which the reeling nip N transfers in the secondaryreeling. On the diagonally upwards directed portion between theadditional roll 11 and the first guide roll 2 the supporting member 1carries the web towards the reeling nip N1. The additional roll can beused to adjust the tension of the supporting member. In addition, a roll12 in contact with the supporting member outside the loop is presented,which can be used as a guiding roll, which positions the supportingmember 1 in the lateral direction by means of the movement in its oneend (arrows).

The advantage in the embodiment of FIGS. 7 to 11 is that, only the firstguide roll 2 of the rolls inside the loop is to be moved when desiringto change the mutual location of the guide roll 2 and the reeling nip N1in the primary reeling, and the other rolls can remain in the sameposition in all stages.

The plane-like flexible supporting member 1, which forms a closed loopby means of two or more rolls, is advantageously air permeable, forexample a wire. However, also such supporting members that are airimpermeable are within the scope of the invention, for example, beltshaving closed surface. The supporting member is of the same structure inthe lateral direction of the machine, i.e. it corresponds to the widthof the web being reeled. However, the scope of the invention alsoincludes the idea that the loop is formed of several loops travellingnext to each other in parallel relationship, while the general geometryin side-view is exactly the same as in FIGS. 2 to 11. Thus, the tensionof the loops can, for example, be adjusted independently according tothe principles known from the publication EP-860391.

The primary reeling device 8 is preferably movable vertically up anddown, in which case in the upper position it fetches a new reel spool 5from the storage and in the lower position forms a change and primaryreeling station. It is, however, possible that the primary reelingdevice, which keeps the new reel spool during change and primary reelingstage, is completely stationary in its position. In this case, the newreel spool is brought with special transfer members, for example, acrane, from above to the primary reeling device. Thus, the reeling nipN1 must be closed by moving the first guide roll 2.
